OBJETIVO: Relatar uma série de casos de pacientes com mediastinite descendente necrosante (MDN) tratados com cirurgia torácica minimamente invasiva. MÉTODOS: Relatamos os casos de três pacientes com MDN submetidos à desbridamento mediastinal através de cirurgia torácica videoassistida no Hospital São Paulo, São Paulo (SP), desde a sua admissão até o desfecho final. RESULTADOS: Os três pacientes apresentaram boa evolução pós-operatória, com tempo médio de internação de 16,7 dias. CONCLUSÕES: Concluímos que a videotoracoscopia é uma técnica efetiva para a drenagem mediastinal no tratamento da MDN, com os benefícios da cirurgia minimamente invasiva: menos dor pós-operatória, menor liberação de fatores inflamatórios, retorno precoce às atividades diárias e melhores resultados estéticos.
Advanced age, greater maximum SPN diameter, and spiculated margins were significantly associated with the diagnosis of SPN malignancy. Our analysis shows that, although both mathematical models were effective in determining SPN malignancy in our population, the 1997 model was superior.
Introduction: Low-grade fibromyxoid sarcoma (LGFMS) is a rare special subtype of fibrosarcoma, it is more common in the trunk and proximal limbs. First described by Evans in 1987, this tumor is also named Evans tumor. Diagnosis of LGFMS may be quite challenging, either due to the low suspicion rate of the tumor or low specificity of its morphological pattern and immunohistochemical profile, a phenomenon that is magnified when tumor location is less usual, such as in the chest wall. The present article presents a challenging case of LGFMS of the chest wall. Case report: Female, 58-year-old patient was referred to the oncology referral clinic with a breast tumor. Diagnostic investigation included imaging tests (breast US and chest CT scan) and core needle biopsy. CT scan revealed the epicenter of the tumor in the left anterior thoracic wall. Biopsy to evaluate the histologic type of tumor was carried out and the result was inconclusive. Therefore, surgical excision of the tumor was performed. Histopathology and immunohistochemistry studies of the surgical specimen confirmed the diagnosis of LGFMS of the chest wall. Currently, after 36 months of the surgical excision, the patient is still doing well and continues under clinical follow-up. Conclusion: Although the diagnosis of LGFMS of the chest wall is challenging, it should be done correctly, since these cases require a long and thorough clinical follow-up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
